Re: Newbie help -- ported box

Hey I'd buy a box, but sadly I'm a high schooler with a limited budget. :P

Anyways, I think it'll be a good thing to figure out how to do now so I can make better boxes if I upgrade my system later. Plus, my dad's a carpenter so I have all the tools I'll need, and he can help me.

Re: Newbie help -- ported box

It is nice to see someone new here actually do research before posting.
Here is what I recommend
Have a box designed by an expert here who will basically provide you with a blue print you can follow.
Ram-Designs, Mobile Enclosures are 2 of the guys on here that do designs.
That way you get to learn while still building your own box.

Re: Newbie help -- ported box

Hopefully we don't screw up too much wood. :P

Okay, now I have another question. :P So what I'm thinking now is having the two subs share one port in the middle. If I have them sharing a port do I need to change the port size, like double it? Or should I just make a separate port for each sub and still have them in the middle, just divided?

Re: Newbie help -- ported box

Crispin, how much would it cost to have one of those guys design a box for me?

EDIT: Ignore that, checked Ram Design's website. I'll think about it but I'm still going to look into how to design my own box. :P I'm just cheap like that. But I will seriously consider Ram Design. He looks like he does good work.

Re: Newbie help -- ported box

Have both subs share the same airspace and do one large port. I'd do the port on a side as opposed to between the subs. Just change the port size/number/etc. on winISD and it'll cough up the correct length and let you know if your port velocity is too high or not.

Re: Newbie help -- ported box

the port area is determined by the available air space that is inside the box. Most people will say use 12-16 in^2 of port area per cubic foot of internal airspace. so say you need 4 feet^3 of airspace, after displacement, and you decide to have 12 in^2 of port area per cubic foot. that would yield 48 in^2 of port. from there use WinISD to find out the length of port you would need......

Re: Newbie help -- ported box

Its easiest to just put the port to 1 side of the box when doing your first slot port. You could always use 2 4inch pvc pipes as well. I prefer to use round ports cuz you just cut the hole out and drop in the tube ans glue around it and you're done.
